Double Sheet Bend
The sheet bend (also known as becket bend, weaver's knot and weaver's hitch) is a bend. It is practical for joining lines of different diameter or rigidity. It is quick and easy to tie, and is considered so essential it is the first knot given in the '' Ashley Book of Knots''. Additionally, it is one of the six knots given in the International Guild of Knot Tyers' Six Knot Challenge, along with the clove hitch, bowline, reef knot (square knot), round turn and two half-hitches, and sheepshank. The sheet bend is related in structure to the bowline; like the bowline, it has a tendency to work loose when not under load. For increased security, it is sometimes recommended that one add another turn in the smaller end, making a double sheet bend; in most cases, however, a single sheet bend should suffice. As a bend, its advantages lie in its simplicity and non-jamming properties. It is commonly taught in Scouting. Definition The term "sheet bend" derives from its use bending r ...

Bowline
The bowline ( or ) is an ancient and simple knot used to form a fixed loop at the end of a rope. It has the virtues of being both easy to tie and untie; most notably, it is easy to untie after being subjected to a load. The bowline is sometimes referred to as ''King of the knots'' because of its importance. Along with the sheet bend and the clove hitch, the bowline is often considered one of the most essential knots. The common bowline shares some structural similarity with the sheet bend. Virtually all end-to-end joining knots (i.e., bends) have a corresponding loop knot. Although the bowline is generally considered a reliable knot, its main deficiencies are a tendency to work loose when not under load (or under cyclic loading), to slip when pulled sideways, and the bight portion of the knot to capsize in certain circumstances. To address these shortcomings, a number of more secure variations of the bowline have been developed for use in safety-critical applications, or by s ...

Warp (weaving)
Warp and weft are the two basic components used in weaving to turn thread or yarn into fabric. The lengthwise or longitudinal warp yarns are held stationary in tension on a frame or loom while the transverse weft (sometimes woof) is drawn through and inserted over and under the warp. A single thread of the weft crossing the warp is called a ''pick''. Terms vary (for instance, in North America, the weft is sometimes referred to as the ''fill'' or the ''filling yarn'').Barber (1991), p. 79 Each individual warp thread in a fabric is called a ''warp end'' or ''end''.Burnham (1980), pp. 170, 179 Inventions during the 18th century spurred the Industrial Revolution, with the "picking stick" and the " flying shuttle" ( John Kay, 1733) speeding up the production of cloth. The power loom patented by Edmund Cartwright in 1785 allowed sixty picks per minute. Etymology The word ''weft'' derives from the Old English word ''wefan'', to weave. ''Warp'' means "that which is thrown away" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Bend Knots
This is a list of bends. A bend is a knot used to join two lengths of rope. They are used in a variety of situations, including climbing, sailing, and securing loads. Bend knots are classified based on their ability to be tightened or released, their resistance to slipping, and their strength. Some common types of bend knots include the double fisherman's knot, the double overhand knot, and the double figure-eight knot. Bend knots are important because they allow two ropes to be securely joined together, enabling the combined ropes to support weight or transmit force. It is important to choose the appropriate bend knot for the specific task at hand, as some bend knots may be stronger or more secure than others. The sheet bend is the classic bend. Misuse of reef knot as a bend The common reef knot (square knot) is sometimes mistakenly tied as a bend. When used as a bend rather than a binding knot, the reef knot will capsize under sufficient tension. For this reason, the reef k ...

Butterfly Bend
The butterfly bend is a knot used to join the ends of two ropes together. It is the analogous bend form of the butterfly loop, in that it is the butterfly loop with the loop cut. The observation that the butterfly loop is secure enough to isolate a worn or damaged section of rope within the loop indicated that the bend form of the knot would be similarly secure. History When Phil D. Smith made the first known presentation of the Hunter's bend in 1953 (under the name "rigger's bend"), he described it as a modification to the butterfly bend. While the bend form had been known to mountaineers, nautical rigger Brion Toss brought the knot to a wider audience when he published it in 1975. Unaware of the earlier publication, Toss called the butterfly bend the strait bend after the Strait of Juan de Fuca. Tying The butterfly bend can be tied using a subset of the methods used for tying the loop form by holding the two rope ends together and treating them as if they were a single bight ...

Topology
In mathematics, topology (from the Greek language, Greek words , and ) is concerned with the properties of a mathematical object, geometric object that are preserved under Continuous function, continuous Deformation theory, deformations, such as Stretch factor, stretching, Twist (mathematics), twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or passing through itself. A topological space is a set (mathematics), set endowed with a structure, called a ''Topology (structure), topology'', which allows defining continuous deformation of subspaces, and, more generally, all kinds of continuity (mathematics), continuity. Euclidean spaces, and, more generally, metric spaces are examples of a topological space, as any distance or metric defines a topology. The deformations that are considered in topology are homeomorphisms and homotopy, homotopies. A property that is invariant under such deformations is a topological property. Basic exampl ...

Bight (knot)
In knot tying, a bight is a curved section or slack part between the two ends of a rope, string, or yarn.. "Any slack part of a rope between the two ends, particularly when curved or looped." A knot that can be tied using only the bight of a rope, without access to the ends, is described as in the bight. The term "bight" is also used in a more specific way when describing Turk's head knots, indicating how many repetitions of braiding are made in the circuit of a given knot. Bight vs. open loop Sources differ on whether an open loop or U-shaped curve in a rope qualifies as a bight. treats bights and loops as distinct, stating that a curve "no narrower than a semicircle" is a bight, while an open loop is a curve "narrower than a bight but with separated ends". However, ''The Illustrated Encyclopedia of Knots'' (2002) states: "Any section of line that is bent into a U-shape is a bight." Slipped knot In order to make a slipped knot (also slipped loop and quick release knot), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half Hitch
The half hitch is a simple overhand knot, where the working end of a line is brought over and under the standing part. Insecure on its own, it is a valuable component of a wide variety of useful and reliable hitches, bends, and knots. Two successive half hitches tied around an object makes up the common clove hitch. Two successive half hitches tied around the standing part of a rope is known as two half-hitches or double half hitch. One instance where a half hitch stands on its own without additional embellishment is when added to a timber hitch to help stabilize a load in the direction of pull. A timber hitch is tied on the far end of the load to bind it securely and a half hitch made at the forward end to serve as a guide for the rope. In this instance, the half hitch combined with a timber hitch is known as a killick hitch or kelleg hitch. The knot is attractive to the eye and so is used decoratively for French whipping which is also known as ''half hitch whipping''. S ...

Scouting
Scouting, also known as the Scout Movement, is a worldwide youth movement employing the Scout method, a program of informal education with an emphasis on practical outdoor activities, including camping, woodcraft, aquatics, hiking, backpacking, and sports. Another widely recognized movement characteristic is the Scout uniform, by intent hiding all differences of social standing in a country and encouraging equality, with neckerchief and campaign hat or comparable headwear. Distinctive uniform insignia include the fleur-de-lis and the trefoil, as well as merit badges and other patches. In 1907, Robert Baden-Powell, a Lieutenant General in the British Army, held a Scouting encampment on Brownsea Island in England. Baden-Powell wrote '' Scouting for Boys'' (London, 1908), partly based on his earlier military books. The Scout Movement of both Boy Scouts and Girl Scouts was well established in the first decade of the twentieth century. Later, programs for younger children, such as ...
